Got my new E3D All-Metal Hotend V4 - (Updated with Mounted Pics) (Page 3 of 9)

Ok cheers thanks

Did yours fail adrian?

Nope - if you recheck the thread a few posts back, there is a bad batch of heater cartridges that are both under-spec and Not-Round... (great combo ). Sanjay did a world-wide replacement to all owners of the E3D with both known good cartridges, and properly round ones (not ovals ).

Good news there!

Make sure you have Lawsy's Mk4 printed , and I found cain666's support neccesary due to the slightly longer length of the extruder meaning it had a bit more of a pendulum effect...

So one of these:

And one of these:

My E3D have now shipped.

I will try and finalise the mk5 extruder very soon (which has a retaining clip to prevent wobble) to prevent wobbling problems.

It works fine without it for operation and worst case just wrap the top in a little kapton tape. You can also just slow the print

The support is needed though I personally found to ensure good detail at any reasonable speed as the wobble encouraged overshoot artifacts (such as perpindicular walls penetrating perimeters)

So don't worry too much, but definitely get to it till the Mk5 arrives

I have a June 4th order, no shipping notification.

Elmoret.
Your 2 have shipped I am reliably informed. We just need to scan in hundreds of barcodes into our shipping/tracking notification system to get the notifications out. We are prioritising actually shipping stuff over getting notifications out - which means that your notification is going to come later. I know this isn't perfect, but as we only have a finite amount of time in the day we believe that it is more productive for us to spend our time packing/shipping as opposed to scanning/notifying.

Concerning water cooled and multi-nozzle hotends

Because there seems to be a bit of speculation/confusion surrounding this I am going to let the cat out of the bag.

We have on the way a small prototype run of a 4 nozzled, water cooled, bowden fed hotends.

We are calling this new hotend "Kraken" - A multi tentacled water borne monster! 

The total footprint of the hotend is only 30*40mm in XY plane, the Z height from top to tip is under 40mm, and the 4 nozzles are arranged in a rectangle only 20mm*18mm apart. The weight without electronics looks to be around 110 grams, which is barely the weight of 2x E3Dv5 hotends. Each nozzle to have separate temperature control. Each nozzle can be individually levelled and adjusted in height to be planar with the bed in a very easy and quick way.

The small size and weight despite 4 nozzles is due mainly to the high efficiency of water cooling, even with only a tiny amount of water flow and a small cooling channel we still have a massive excess of cooling capacity. The second reason is a new way of mounting/gripping bowden tubes which has all the convenience and grip of pneumatic push-fit couplers, but with significantly less bulk and weight.

We intend to keep the price reasonable, and below the price for buying the equivalent number of E3Dv5.

But to be clear - Kraken is not a replacement for the normal v5 hotend, which will remain our main product that suits most users. The Kraken is designed purely for multi-nozzle bowden feed applications. Futhermore it is not finished! We will be shipping the majority of our beta prototyping run to trusted testers. I expect problems to occur and tweaks to be necessary. I will start a separate thread once things are ready, and the final version of Kraken will be developed in a public/interactive manner so the community can input what it wants/needs so that we can give you guys what you want.

Kraken will be open-source when sold publicly.

Cheers,
Sanjay

Oh awesome! We are actually wanting to buy a filastruder to create more exotic filaments for printing experiments. Didn't realise you are behind that project.

We really want some PEEK and FEP filament. Printing PEEK or Ultem type polymers would be a massive step forward for open-source 3DP. Combined with FEP we think it might be possible to actually print a J-Head type hotend minus the brass nozzle tip and electronics.

Blends and additives are also something we are looking at playing with. But our main priority is that we want to test and be able to say that E3Dv5 prints [insert list of materials] and that we have tested them to work. This should then enable people buy and experiment with confidence in a polymer that suits their application.

Well, the V4.1 will print PLA, Soft-PLA, ABS, HIPS and Polycarb ... Here it is busting out some Polycarb

Woohoo! my E3Ds are on their way! Thanks sanjay!
